Abstract

Pathogenesis-related (PR) genes are useful molecular markers, and gene expressions are activated in the reaction of plant-parasitic nematodes. Determining PR gene expression and resistance reaction of P. vulgaris genotypes against root-knot nematode are valuable for understanding plant-nematode interactions. However, resistance reactions of P. vulgaris genotypes and gene expression of host-nematode interactions have not been fully understood. Therefore, this study aimed to determine the expression of PR genes during the infection of M. incognita on resistant and susceptible bean varieties at 1,3,5,7 days post-infection (dpi). Results revealed that one genotype gave a reaction as “immune,” and numerous genotypes were susceptible. The expression of PvPR1 and PvPR2 genes reached the highest peak at 1 dpi in nematode infected immune plants, and the expression of PvPR1 reached 5 dpi in susceptible plants. In conclusion, PR genes involved in nematode resistance and parasitism and the immune common bean genotype have great potential in breeding programs and understanding the exact location of resistance on gene map would be advantageous as future work.
